Reverse Engineering An AlGaAs/InGaAs PHEMT With FastBlaze

FastBlaze is an ultra-fast physical MESFET and HEMT simulator which incorporates advanced physical models. By designing the simulator and its framework specifically for these devices, Silvaco has optimized device simulation algorithms and data structures for high speed without sacrificing the accuracy of the physical models.

ATLAS Field Dependent Mobility: Model Parameters for (0001) 6H-SiC and (0001) 4H-SiC

For high temperature, high power applications Silicon Carbide (SiC) continues to be a useful material for device fabrication because of its wide band gap, high breakdown field, and high thermal conductivity [1]. Some common power devices utilizing SiC include the following: Schottky and p-n junction diodes, thyristors, and UMOSFETs. Recent research has further contributed to the characterization of the electrical transport properties of 6H-SiC and 4H-SiC [2].

Investigating Two Dimensional Implantation Effects Using The BCA Model

The Monte Carlo Binary Collision Algorithm (BCA) implant module in ATHENA was introduced in an earlier article [Simulation Standard Vol 10, #5, May 1999] which discussed the accuracy of the simulation model compared to one dimensional measurements using Secondary Ion Mass Spectroscopy (SIMS). In this article we discuss the two dimensional effects that can be simulated using the BCA module that cannot accurately be simulated using analytic models.

Hints & Tips January 1999

A. UTMOST III SOI module has three routines for characterization of the parasitic BJTs of SOI devices. These routines are "IC/VCE", "Gummel" and "INT_BJT" All routines require to have 5 terminal devices with bulk connection for data collection.

VBIC Version 1.2 Released in SmartSpice and UTMOST III

The latest VBIC bipolar model v1.2 of Sep 24 1999 has been integrated into SmartSpice and UTMOST III. It can be invoked by specifying the model selector LEVEL=5 and the version selector VERSION=1.2. in the .MODEL card. This new version becomes the default VBIC model.

RF CMOS Device Modeling: BSIM-Based Physical Model with Root-Like Construction Approach – Small Signal Modeling

A novel extraction method of high frequency small-signal model parameters for MOSFET is proposed. From S-parameter measurement, this technique accurately extracts the MOSFET model parameters including the charge conservation capacitance parameters. To consider charge conservation, nonreciprocal capacitance is considered. The modeled S-parameters fit the measured ones well without any optimization after parameter extraction.
